UCC28056 Product details

Description

The UCC28056 device drives PFC boost stages based on an innovative mixed mode method that operates in transition mode (TM) at full load and transitions seamlessly into discontinuous conduction mode (DCM) at reduced load, automatically reducing switching frequency.

Features

1 Ultra-low no-load input power enables < 80-mW standby power at 230 VAC in PFC+LLC system.
Excellent light load efficiency and high efficiency over wide range of load due to multi-mode TM and DCM control.
Enables low system cost through FET Drain valley synchronized turn-on which eliminates need for second winding on the boost inductor.
Enables compliance to green power standards without disabling PFC.
EuP Lot 6 Tier 2, CoC Ver. 5 Tier 2, Energy Star.
